Finding a quality bimini top for your havoc boat is usually the first thing on the list once the summer heat really starts to kick in. If you've spent any time out on the river or the lake in a Havoc, you know these boats are built for performance and getting into tight spots that other boats can't touch. But as much as we love that open-deck feel, sitting in a metal boat under a July sun can feel a lot like being a piece of bacon in a frying pan.
Adding a bimini isn't about turning your rugged duck boat into a slow-moving pontoon; it's about making sure you can actually enjoy your investment when the thermometer hits ninety. Let's be honest, nobody has a good time when they're nursing a third-degree sunburn by noon.
Why Your Havoc Needs a Bit of Cover
Havoc boats have earned a reputation for being tough, fast, and agile. Whether you're running a mid-section tiller or a side console, these boats are designed with a specific "no-nonsense" aesthetic. Because of that, some guys feel like adding a top might mess with the boat's look. But the truth is, a well-fitted top doesn't just provide shade—it extends your season.
Think about those days when you want to take the family out or just spend a long Saturday fishing for crappie. Without some shade, you're looking at a two-hour trip before everyone's ready to head back to the truck. With a bimini, you can stay out all day. Plus, it's a lifesaver when a random afternoon rain shower pops up, which happens more often than most of us would like to admit.
Picking the Right Canvas Material
When you start looking for a bimini top for your havoc boat, the first thing that's going to hit you is the variety of fabrics. It's easy to just grab the cheapest one on the shelf, but you'll probably regret that after one season.
Most people choose between two main options: Polyester and Sunbrella.
Polyester is usually the more affordable choice. It's lightweight and does a decent job of shedding water. If you go this route, make sure it's a "solution-dyed" polyester. This means the color is part of the fiber itself, not just sprayed on the top. If it's not solution-dyed, that deep black or olive drab color will turn a weird shade of chalky purple after a month in the sun.
Sunbrella, on the other hand, is the gold standard. It's a bit more of an investment, but it lasts forever. It's incredibly breathable, which is actually a big deal. If the fabric doesn't breathe, the heat gets trapped right under the top, and it feels like you're sitting in a sauna. Sunbrella stays cool, resists mold, and keeps its color even if you leave it out all summer.
Aluminum vs. Stainless Steel Frames
Since Havoc boats are aluminum, you'll want to think about what kind of frame you're putting on those gunnels. Most people go with an aluminum frame. It's lightweight, it matches the boat's construction, and it's plenty strong for what most of us are doing.
If you're running in saltwater or you're just someone who wants the absolute beefiest setup possible, you could look at stainless steel. It's much heavier and more expensive, but it's nearly indestructible. However, for a 16 or 18-foot Havoc, a high-quality 1-inch thick aluminum frame is usually the sweet spot. It won't weigh the boat down or affect your hole shot too much, but it'll stay steady when you're cruising.
The T-Rail Mounting Factor
One of the coolest things about a Havoc boat is the integrated T-rail system on the gunnels. It makes mounting accessories a total breeze. When you're looking for a bimini, don't just settle for the standard "drill-it-into-the-metal" mounts.
You can find (or easily modify) mounting brackets that slide right into that T-rail. This is a huge win for a few reasons: 1. No extra holes: You don't have to drill into your beautiful boat. 2. Adjustability: You can slide the bimini forward or backward depending on where you're sitting or how many people are on board. 3. Easy Removal: When duck season rolls around and you need that top out of the way, you just loosen the bolts and slide it out. No permanent hardware left behind to trip over or snag a decoys' line.
Getting the Measurements Right
There's nothing that looks worse than a bimini top that's six inches too wide or way too tall. It makes the boat look lopsided and creates a ton of wind drag. To get the right fit, you need to measure the mounting width, not the width of the boat itself.
Measure from the center of the rail on one side to the center of the rail on the other. Most bimini tops come in width ranges (like 67" to 72"). You want to find one where your measurement falls right in the middle of that range.
As for height, don't go too tall. A top that's 48 inches high (from the mounting point) is usually plenty. It gives you enough room to stand up if you need to, but it stays low enough to provide actual shade. If the top is too high, the sun just hits you from the side anyway, and the wind will catch it like a sail.
Speed and the "Fly-Away" Risk
Let's talk about speed. Havoc boats are fast. If you've got a 50hp or a 60hp on the back of a 1652, you're moving. Most bimini tops are rated for about 35-40 mph while they're open. If you're pushing 50, you really shouldn't have the top up.
When you're running wide open, it's best to fold the top down and put it in its storage boot. Most tops come with these zippered sleeves. It keeps the fabric from flapping in the wind, which is what eventually tears the seams or bends the poles. If you do plan on running with it up, make sure you have sturdy rear support poles instead of just nylon straps. Support poles hold the frame rigid and stop that annoying "shaking" that happens at higher speeds.
Choosing a Color That Fits
Since most Havoc boats come in some form of camo—whether it's Timber, Marsh, or a solid OD Green—you probably don't want a bright white or royal blue top. It just looks out of place.
Most guys go with Black, Charcoal, or Olive Drab. Black looks sharp and actually hides dirt and grease really well. Don't worry about it being "hotter"—the shade it provides underneath far outweighs any heat the fabric itself absorbs. If you can find a camo pattern that matches your boat's wrap or paint, even better, but solid dark colors usually look the cleanest.
Installation Tips for the DIY Crowd
Installing a bimini top for your havoc boat is a totally doable Saturday morning project. You'll need a tape measure, a drill (if you aren't using the T-rail), and maybe a buddy to help hold the frame while you're leveling it out.
The biggest tip I can give is to "dry fit" everything before you tighten any bolts. Set the top on the boat, have someone hold it up, and make sure it doesn't interfere with your throttle, your seats, or your fishing electronics. You'd be surprised how many people install a top and then realize they can't full-swing their fishing rod or that the back of the top hits their motor when they trim up.
Maintenance to Make it Last
Once you've got it on, don't just forget about it. Aluminum and fabric both hate sitting under wet leaves or bird droppings. If you get some grime on the canvas, just hit it with some mild soap and a soft brush. Whatever you do, don't power wash it. You'll blast the waterproof coating right off the fibers.
Every few months, check the mounting bolts. Vibration from the engine and the water can loosen things up over time. A little dab of blue Loctite on the threads can save you from losing a screw in the middle of the lake.
The Bottom Line
At the end of the day, putting a bimini top for your havoc boat is one of those upgrades you'll wish you had done sooner. It doesn't make the boat any less "tough"—it just makes you a lot smarter for not wanting to deal with heatstroke.
Whether you're out there waiting for a bite or just cruising the timber with some friends, having that patch of shade makes the whole experience way more relaxed. Just measure twice, don't cheap out on the fabric, and make sure it's secured well enough to handle the speed that Havocs are known for. Once it's on, you'll wonder how you ever survived those triple-digit afternoons without it.
